//! \brief Drawing state used in the draw methods of MPxSurfaceShapeUI
/*!
This class is used by the getDrawRequests method of MPxSurfaceShapeUI
to specify the current object drawing state for a user defined shape.

This getPrototype method is used to construct a draw request object
based on the current draw state for the object.

See MDrawRequest for more information.
